GRAIN-CUTTING MACHINE WITH AUTOMATIC SCOOPS'.

Application ledJ'lanuary'Zll, 1923. Serial No. 614,589.

T aZZ whom 'it may concewt Be it known that I, DAVID GUELBAUM,

a citizen 0f the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a' certain new and useful Grain-,Cutting Machine with Automatic Scoops, of which the following is a specification. i My invention of a grain cutting machine with automatic scoops has for its object the cutting up of cereal grains, such las wheat, rye, barley, into particles, coarse or fine,

. without cracking or crashing of the gr-ains and without powdered'wastage, by lmeans of rotary knives and scoops automatically adjusting themselves to the direction vof ro'- tation of said knives, so that said knives may be worked in either direction or reciprocally.` And reference is here made to theapplicants previous application for a Grain cutting machine, filed ()ct. 21, 1922, Ser. No. 596,176. t p y, My invention comprises the above novel features, embodied in combinations and constructions as hereinafter set forth and claimed, and as illustrated in the accompanying drawings, in which similar characters designate the same corresponding parts in all the views.

Fig.v l is a vertical section of my grain cutting machine. l l y Fig. 2 is a cross section of same, showing the cutting edges and scoops. y

Fig. 3 is afractional top view, showing scoop and pivot.

Fig. 4 is a magnified section of scoop and pivot. f As seen on Fig. 1, my grain cuttingumachine consists of the grain hopper 1 having an 4offset cylindrical flanged top 2 and a slightly tapered bottom 3 with an open neck 4 in the centre andl provided with the supporting brackets 5.

Into said neck 4 and resting on same is fitted the stationary outer eylinder- 6 held securely by the screws 7 passing through the cast on bosses 8. This cylinder is pro-A v vided with longitudinal slots separated by the triangular strips 9, as shown in elevation and cross section on Figs. V1 and2.

. Inside this stationary outer cylinder 6 is fitted slidingly the inner rotary cutting cylinder 10 provided with similar longitu dinal slots with sharp beveled cutting edges 11, as shown on Figs. 1 and 2. The top of thisinner cutting Cylinder' 10 fits intothe bottom of the cone shaped cover 12 held securely by the screws 18 passing'through the cast ron bosses 14, as shown on Figs. `1 and 4.

This cover 12 terminates at its top with the hub 15 intov which is key-seated the bolt or gudgeon 16 fastened likewise to the hub 17 of the hand wheel 18, both said hubs 15 and 17 being securely held together bythe nut 19.

The rim 20 of said hand wheel is connected to its hub by the several arms 20 and rests on the offset top flange 2 yof the hopper l'kitting slidinglyV into same, as shown onF ig. 1. The rim `2() isheld fast toits seat by the clips 2l with lthe screws 22 screwed into the lugs 28 cast on the top flange of the hopper 1, as shown on Figs. l and 3. p Y l' Thus the hand vwheel 18 carrying the cone shaped cover 12 with the cutting cylinder 10 is reliably supported and guided, taking off all side strains from' the cutting cylinders. By unfastening the clips 2l, the h-and wheel 18 with the cover'12 and the inner cylinder 10 can bodily be taken out of the grain hopper.

To one of the arms 20 near the rim is fastened the handle 24 for rotating the hand wheel 18 together with the cover 12 and the inner cutting cylinder 10.. For the same purpose the gudgeon 16 may be extended Iabove the hand wheel and a pulley attached vtoit fora belt drive, if so desired, as indicated on Fig. l, showing the. gudgeon broken olf 0n top.

The hand screw 25 passing through the lug 28 and piercing into the rim 20, shown on Fig. 1, is provided for holding the handy wheel 18 fixed, when the machine is not working, in such a position, that the strips of the inner cylinder 10 cover the slots of the outer cylinder 6, as shown on Fig. 2, and no grains can pass through the slots. .t The cone shaped cover 12 is provided with the cast on lugs 26, shown on Figs. 1 and 8, and magnified on Fig. 4. On these lugs rest the flat tops 28 0f thelscoops 27,

consisting of bent plates, as shown. Into the lugsv 26 are Iscrewed in the bolts or pivots 29 passing through the plate ringl 30 held at a. fixed distance from the lugs by the separator rings 3l, around which the fiat tops 28 of the scoops 27 can thus freely turn on their central axes Without buckling. The plate ring 30 is provided With the projections 32 opposite `the pivots 29; after the pivots are tightly screwedim the projections 32 lare bent up against the heXagon heads of the pivots, as an Figs. 4L and 3, so they cannotget loose. U

. The grain hopper 1' is `shown on Figs. 1

and 2 as resting with. its brackets 5 on Wooden blocks or pedestals 5, to Which they of the grain against them willv be kept in the fixed position as shown in plan on F igs. 2 and 3, shovelin'g and thrusting they grains through the slots of the stationary vcyiinder G Where they are met and cut by the revolving knivesll of the inner cylinder l0. Reversing the direction Aof rotation, the pressure ofthe grains will be on the opposite side of the scoops, and they v vill lauto- -inatically assume the position as shovvn on Fig. 2 in dash and dot, turning around their axes O. j V

Should one of the scoops assume at the start the exact middle position, at .Which the `grain pressure upon either side of it is thesame, that scoop may be pushed into the right position by hand, While in vtherunning condition itsown impulse in the procless of reversing will overcome that dead point, similar to -a single cylinder steam enj gine, 1f the crank at the starting happens to lbe von the dead centre, the flywheel is given .j al'push, While in thev runningcondition its ovvn impulse carries the crank over the dead centres.

`What l claim, is: v l. A grain cutting'machine, comprising a grain hopper r'with an offset flanged top .supporting the rim ofa hand Wheel and having a tapered bottom with an open neck in centre, a stationary slotted cylinder fastened inside of said hopper and a rotating slotted cylinder with sharp cutting edges inside of lsaid stationary cylinder', a cone shaped cover with its top fastenedA to the hub of said hand Wheel and holding fast in its bottom the top of said rotating cyl-` inder, scoops for thrusting the grains into the slots ofv said stationary cylinder, means for supporting said scoops and automatically adjusting them to the direction of rotation of said hand Wheel, substantially as and for the purpose specified. n
